Do repo custom workflows respect pre workflow hooks

[paymog]

If i define a pre workflow hook for a repo in my server config file AND I have custom workflows in the repo level atlantis.yaml, will the pre workflow hooks be respected by the custom workflow?

Yes, pre workflow hooks defined in your server config file are always respected and executed before any workflow runs, including custom workflows defined in the repo-level atlantis.yaml. The execution of these hooks is independent of whether you use the default workflow or a custom one—there’s no code path that disables or overrides server-level pre workflow hooks when a custom workflow is present. If a pre workflow hook fails and you have the fail-on-pre-workflow-hook-error flag set, the main workflow (custom or default) will not run; otherwise, Atlantis will proceed with the workflow even if the pre hook fails. You can see this logic in the pre workflow hooks runner implementation and the command runner orchestration.

@dosu do the pre workflow hooks run once per custom workflow or once per entire atlantis run for a given commit on a given PR?

Pre workflow hooks run once per Atlantis command execution (like plan or apply), not once per custom workflow or per project. So if you trigger a plan or apply on a PR, the pre workflow hooks execute a single time before any workflows (custom or default) for that command, regardless of how many projects or custom workflows are involved. If you run both plan and apply, the hooks will run once for each command. This is handled in the command runner orchestration and pre workflow hook runner logic—there’s no code path that would cause them to run multiple times per workflow or project within a single command execution. You can see this in the orchestration logic here and the hook runner implementation here.
